I'd add to that that H will be far better off, actually NEEDS for OW to go through the rage and anger and grief, to understand that he can face it and live through it. Not only because your response to his betrayal and her response to his not-betrayal-because-the-whole-thing-was-built-on-sand-and-wrong will be so very different, though that will also be clear. But because he has to learn to face the consequences, feel remorse, see the impact his actions have on others, survive the pain, grow from the pain. There is no way for that to go smoothly, and there shouldn't be a way for that to go smoothly. The ugliness needs to be totally exposed, all the sand washed away in the hurricane, before he can ever try to build his house again on the rock.
I believe I will see the bounty of the Lord in the land of the living. Wait for the Lord with courage. Be stouthearted, and wait for the Lord.
